There are two methods of solving a system of equations algebraically. We cover the second one in this lesson. The elimination method involves adding the system's equations together with the goal of eliminating a variable so you can solve to the remaining variable.

Objectives

By the end of this topic you should know and be prepared to be tested on:

5.3.1 Solve a 2x2 linear system of equations algebraically by the elimination method

5.3.2 While solving a system by the elimination method, recognize that the system has no solution

5.3.3 While solving a system by the elimination method, recognize that the system has an infinite number of solutions
